Question

click on each action that will reduce the rate at which the speed of the basket changes. pull with less force pull with more force add an apple to the basket take an apple out of the basket smooth the surface of the table to decrease friction roughen the surface on the table to increase friction

Explanation:

To reduce the rate at which the speed of the basket changes (i.e., reduce acceleration), we use Newton's second law \( F = ma \) (acceleration \( a=\frac{F}{m} \)).

• "Pull with less force": Decreasing force \( F \) decreases acceleration (since \( a\propto F \) for constant mass).
• "Add an apple to the basket": Increasing mass \( m \) decreases acceleration (since \( a\propto \frac{1}{m} \) for constant force).
• "Roughen the surface to increase friction": Friction opposes motion; increasing friction increases the net force opposing the pull, reducing the effective net force and thus acceleration.

Actions like "pull with more force" (increases \( F \), increases \( a \)), "take an apple out" (decreases \( m \), increases \( a \)), or "smooth surface" (decreases friction, increases net force, increases \( a \)) do not reduce the rate of speed change.

Answer:

• Pull with less force
• Add an apple to the basket
• Roughen the surface on the table to increase friction
